Question about Samsung HCM4215W 42" Rear Projection Television
My TV won't turn on... the "lamp" light in the front blinks, then shuts off, then reboots and blinks again, then off, and reboots one last time before all 3 LED light blink together.
I replaced the lamp and replaced the color wheel... The technician said, however, that the color wheel wasn't even starting up. He said that the power supply looked alright because the fans were starting and lights were blinking on, but no color wheel movement. He said that probably meant that the Light Engine needed to be replaced.
However, I'm hoping that I can fix the issue without replacing the entire light engine. The only other parts available for sale are the "tunnel" and the "DMD board"... what ARE the tunnel and DMD board and where are they located/ what do they look like... I feel like the tech may have just been a little mis-informed...
